Hi popeye,
as the exception shows, somehow the service to the classes definition of alfresco can not be accessed:
java.net.SocketException: Software caused connection abort: recv failed
Please call following url:
h t t p : //<server>:<port>/alfresco/service/api/classes/
replace server and port with your installation. There you should get a file as answer!
If that is not accessible please check your installation and firewall settings.
Is everything working, please verify that your connecting against your alfresco deployment (WSDL definitions correct in owbootstrap.xml?).
One important thing which need to be checked, is if you use our defaulft cmis configuration (WEB-INF/conf/cmis), this is preconfigured against the alfresco cloud and you have to change the <AspectRetrieveUrl>-tag value (in owbootstrap.xml).
Hope that helps!
Cheers,
D.evil
